The MAX535/MAX5351 combine a low-power, voltage-
output, 13-bit digital-to-analog converter (DAC) and a
precision output amplifier in an 8-pin µMAX or DIP pack-
age. The MAX535 operates from a single +5V supply
and the MAX5351 operates from a single +3.3V supply.
Both devices draw only 280µA of supply current.
♦ 13-Bit DAC with Configurable Output Amplifier
♦ +5V Single-Supply Operation (MAX535)
+3.3V Single-Supply Operation (MAX5351)
♦ Low Supply Current: 0.24mA Normal Operation
2µA Shutdown Mode
The output amplifier’s inverting input is available to the
us e r, a llowing s p e c ific g a in c onfig ura tions , re mote
sensing, and high output current capability. This makes
the MAX535/MAX5351 ideal for a wide range of appli-
cations, including industrial process control. Other fea-
tures include a software shutdown and power-on reset.
♦ Available in 8-Pin µMAX
♦ Power-On Reset Clears DAC Output to 0V
♦ SPI/QSPI and Microwire Compatible
♦ Schmitt-Trigger Digital Inputs for Direct
Optocoupler Interface
The serial interface is compatible with either SPI™/
QSPI™ or Microwire™. The DAC has a double-buffered
input, organized as an input register followed by a DAC
register. A 16-bit serial word loads data into the input
register. The DAC register can be updated indepen-
dently or simultaneously with the input register. All logic
inputs are TTL/CMOS-logic compatible and buffered
with Schmitt triggers to allow direct interfacing to opto-
couplers.
